A word that originally came from the phrase "tig ol' bitties", meaning big ol' titties, which then got shortened to bitties therefore referring to women's breasts. The word has evolved and recently can be defined as any type of women one finds attractive or wants to "get with".

Definition 1: Hey look at that chick's huge bitties.
Definition 2: -Let's do something tonight. How about we call up some bitties.
-Damn, Look at that group of bitties over there, we better fuck that shit.

Despite the obvious derivation from the word "bitch," the word bitty has no negative connotations. Rather, the inverse is true: "Bitty" is a term for an attractive female, but is not used as a direct compliment or pick up line--it is casual.

Singular: That bitty over there is looking at you man.
Plural: Call up some bitties to come over.

A bitty is an over intoxicated female who frequently roams the trashiest bars and dance clubs in your city. Bitties tend to dance on top of speakers, spill drinks every where, puke, and black out. If you see a bitty on the street she will most likely come up to you and sound really loud and obnoxious, do not be scared because the subtle use of sarcasm will forever render the bitty confused.

A negative term for a preppy female who is very ignorant and proud. A bitty treats others as inferior beings even though they are despised by all their peers. They are usually rich, unintelligent and spoiled.
